Philosophy of Science, understood as a special philosophical discipline, was born only at the beginning of the twentieth century as part of the effort for overcoming the “foundational crisis” that had affected especially mathematics and physics. Therefore, it was conceived as an investigation about the features and reliability of scientific knowledge and for a few decades was deeply marked by the philosophical approach of logical empiricism. This cognitive point of view persisted also when, after Kuhn’s work, the attention focused on (...) the scientific activity in order to understand scientific change and a sociological model replaced the view that empirical adequacy and logical consistency are the factors that determine the change of scientific theories. Ethical, social and political considerations regarding science ware considered inappropriate and potentially dangerous since they violate the alleged “neutrality of science” with respect to values. Nevertheless, the strict intertwining of science and technology in contemporary “technoscience” has produced a wide debate regarding the practical aspect of technoscientific activity that has the intrinsic features of a philosophical debate. Therefore, it is natural and advisable that the entire wealth of the philosophical disciplines be called to contribute to the specific complex discourse of the Philosophy of Science. (shrink)

The emphasis on models hasn’t completely eliminated laws from scientific discourse and philosophical discussion. Instead, I want to argue that much of physics lies beyond the strict domain of laws. I shall argue that in important cases the physics, or physical understanding, does not lie either in laws or in their properties, such as universality, consistency and symmetry. I shall argue that the domain of application commonly attributed to laws is too narrow. That is, laws can still play an important, (...) though peculiar, role outside their strict domain of validity. I shall argue also that, by way of a trade-off, while the actual domain of application of laws should be seen as much broader. At the same time, what I call ‘anomic’ representational elements reveal themselves as central to the descriptive and explanatory power of theories and model: boundary conditions, state descriptions, structures, constraints, limits and mechanisms. I conclude with a brief consideration of how my discussion has consequences for discussion of understanding, unification, approximation and dispositional properties. I focus on examples from physics, macroscopic and microscopic, phenomenological and fundametal: shock waves, propagation of cracks, symmetry breaking, and others. This law-eccentric kind of knowledge is central to both modeling the world and intervening in it. (shrink)

Pierre Duhem can be looked upon as one of the heirs of a tradition of historical and philosophical researches that flourished in the second half of the nineteenth century. This tradition opposed the naïve historiography and epistemology of the positivist school. Beside the positivists of different leanings such as Littré, Laffitte, Wyrouboff, and Berthelot, we find Cournot, Naville, and Tannery, who developed sophisticated histories and philosophies of science focusing on the real scientific practice and its history. They unfolded elements of (...) continuity and discontinuity in the history of science, and enlightened the complex relationship among experimental, mathematical, logical and philosophical components in scientific practice. In Pierre Duhem we find a systematic and vivid interpretation of these meta-theoretical issues, and a meaningful development of a cultural tradition that re-emerged in the second half of the twentieth century.
